Funny you should mention it. I was about to raise a similar question. In PARMLIB, we have SQA=(600K,45M) and CSA=(3200K,400M). After a recent IPL, our ESQA went from 69,120K to 69,152 K. Our ECSA jumped from 409,616K to 410,608K while EPVT was reduced from 1,526,784K to 1,525,760K.
So I lost one Meg of extended private area. The problem is getting the numbers to add up. Init & Tuning is not helping me figure it out, although I suspect an increase in MAXUSERS from 1,000 to 1,200 (with CSCBLOC=ABOVE) may have had something to do with it. If it were due to UCBs, wouldn't I expect to see the increase in HSA? db -----Original Message----- From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] On Behalf Of Andrew Metcalfe Sent: Wednesday, September 17, 2008 9:35 AM To: IBM-MAIN@BAMA.UA.EDU Subject: Size Of SQA At Next IPL Hello Listers We only perform scheduled IPLs of our systems twice a year. During these 6 month periods, there is a large amount of IODF change implemented by dynamic Activate (by another team). We have had a number of occasions when IPLing our systems where the Private area (below) has increased (not so much of a problem till folks start using it and I take it away again) or decreased (big problem as some applications won't start) as a result of the change in SQA size without a compensating change in the CSA= parameter in IEASYSxx to maintain the top boundary of Private. The problem is caused by SQA size being "determined" rather than "specified" at IPL time. Then CSA, which is specified, is bolted on the bottom and rounded to the next Mb boundary. Does anyone know of a programmatic way to determine the approximate size that SQA would be at the next IPL assuming no more Activates are performed? Is it simply a matter of counting the UCBs below 16Mb (via UCBSCAN?) and multiplying by x'112' as per HCD Planning manual? Any pointers gratefully received.
